On April 21, 1898, the United States declared war against Spain. The causes of the conflict were many, but the immediate ones were America's support of Cuba's ongoing struggle against Spanish rule and the mysterious explosion of the U.S.S. Maine in Havana Harbor. It would be the first overseas war fought by the United States, involving campaigns in both Cuba and the Philippine Islands.

president thomas jefferson hoped that the embargo act of 1807 would the united states by demonstrating to britain and france their dependence on american goods, convincing them to respect american neutrality and stop impressing american seamen. instead, the act had a devastating effect on american trade.
